The Voice of China 1MORE piston earphone adopts a subjective and objective tuning method. The objective measurement data of the earphone needs to reach an excellent level, and then compare it with the actual listening sense of the human ear, and constantly fine tune it to achieve the most ideal sound quality style: Luca Bignardi, an international recording artist who has won four Grammy Awards, was invited to participate in the tuning, And many auditions were held: musicians and professional audio professionals, internal tests and public tests, which closely combined objective acoustics with psychoacoustics. Finally, this kind of earphone that can reproduce the sound of the good voice of China is created. Now let's follow the editor to learn more about this earphone.

The outer packing box of the earphone is made of black paper material. The logo of the Voice of China in the upper right corner of the front, together with the outline drawing of the earphone, is simple and charming. The whole package of China Good Sound earphones is dominated by black, and red elements are added, which makes the package become noisy.

    On the back of the package is a brief introduction, parameters and product related information of the Voice of China 1MORE piston headset. It can be seen that the Voice of China 1MORE piston headset is made of precision metal, ergonomically inclined in ear design, dual system intelligent wire control technology, Grammy Award music master tuning, and dual resonant cavity presents a shocking sound effect.

Specifications of the Voice of China 1MORE piston headset.

    The Voice of China 1MORE piston earphone adopts a side pull design. The outer package mainly reflects the Voice of China. You can see that you listen to the world, the world listens to me, and the mobile 1MORE logo when you pull out the jacket. It can be seen from the package that this headset is made by 1MORE for the Voice of China.

    Open the upper cover and you can see the inside bag of the Sohong of the Voice of China 1MORE piston headset. The metal headphone clip on the accessory box is very conspicuous. Everyone knows that the role of the clip can effectively reduce the stethoscope effect.

    Take out the headphone box, and hide the user manual of the headphone and the product introduction of 1MORE at the bottom. The user manual introduces the definition of the wire control button, the winding method and how to replace the ear muff.

    The accessory box contains not only the headset clip, but also a storage bag. The closure of the mesh bag adopts an automatic sealing design. Two elastic steel sheets are built in, which will open when pressed slightly. After the earphone is put in, it can be automatically sealed when the hand is loosened. The handling of this detail is commendable.

    Like the previous piston earphones, the Voice of China 1MORE piston earphones are packed in acrylic boxes.

    On the back of the box are the specifications of the earphone. The impedance of the loudspeaker is 32 ohms, the frequency response range is 20-20000 HZ, the sensitivity of the earphone is 98 dB, and the rated power is 5 milliwatts. The parameters are basically the same as other 1MORE earphones.

    Open the upper cover and you can see the metal parts of the Voice of China 1MORE piston earphone. It is made of aluminum alloy and has a CD texture treatment process, which can vary under light.

    The Voice of China 1MORE piston earphone uses different processes, and found a process drawing about the parts of the earphone on the Internet.

    The ear type winder uses food grade silica gel that meets the FDA inspection standards. The surface is a safe skin friendly hand paint, which has a more delicate and smooth touch. Compared with the past winders, it is smaller, lighter, more beautiful, and easy to store and carry.

    The Voice of China 1MORE piston earphones come with XS, S and L earphones. Before using earphones, select appropriate ear muffs to ensure comfort while ensuring tightness, so as to get a better sense of hearing. Many people may not pay attention to this point. Although standard earmuffs can be suitable for most people, because the diameter and depth of each person's ear canal are different, inappropriate earmuffs may cause sound leakage or easy to fall off when wearing.

The protective sleeve of 3.5mm metal plug is changed from thin cylinder to spindle, which is more suitable for finger range. The metal surface is also treated with CD lines, which can increase the friction when pulling and inserting the plug, and is more conducive to anti-skid.

The ear remote control adopts a three button unilateral design, which is located on the right side of the headphone cable, closer to the face. In this way, you don't have to hold it in your hand while talking. And there are obvious bulges at both ends of the middle key, which can be operated by touching with hands when using, making it more convenient to use. The other side of the remote control is the headset microphone. The functions of the three buttons are as follows: the middle button can answer or hang up when answering a phone call, play or pause when listening to music, press 2 times for the next song, and press 3 times for the previous song. The up and down keys are the volume up and down keys. For Xiaomi mobile phones, you can customize the function of up and down keys in the mobile phone. And it is compatible with Apple and Android systems, suitable for most mobile phones.

    The splitter also adopts aluminum alloy CD grain treatment, and different wires are used on both sides. The wire material close to the ear is made of TPE material, which is soft, smooth, and feels natural after contacting with the face skin. The other end is made of braided wire, which is not easy to wind. This kind of wire is mainly designed to prevent winding and effectively reduce the "stethoscope effect". 1MORE piston earphone wire is still wrapped with tensile pull and anti winding Kevlar fiber.

    The cavity design of the Voice of China 1MORE piston earphone has greatly changed from the appearance of the previous piston earphone. The aluminum alloy process and surface sandblasting process are also used, but the Voice of China 1MORE piston headset adopts a new shape design. As for the distinction of sound channels, it is not only the sound channel logo on the two earphones, but also the bulge on the edge of the right earplug. You can distinguish the left and right sound channel earplugs by touching them with your hand, without looking at the logo. Of course, it is more intuitive to distinguish left and right sounds by wire control.

    The in ear metal surface of Voice of China is anodized. The left and right earphones are laser engraved with 1more and Voice of China logo, and the other side is left and right channel logo. 80% metal shell is adopted, and the main body is made of metal. The part near the ear is made of plastic, which is very warm in design. If it is winter in the north, the cold all metal earphone ears will be unwilling, and will also increase the weight to wear.

    The whole earphone of Voice of China 1MORE piston headset looks very layered. The two-color processing of the earplug sleeve echoes the color matching of the earphone cable. The unique details are unforgettable. Ergonomically designed, the earplug fits the ear canal. The two different bevel designs are more suitable for the ear canal of the human body, making it more comfortable to wear and not easy to slip off. The most important thing is that you don't feel tired even if you wear your ears for a long time.

    Conical cylindrical cavity, precision sandblasting. Both sides of the cavity are drilled and cut in high light and the handle are in one go, with a sense of hierarchy. The 1MORE hoop iron earphone also adopts this simple and atmospheric appearance.

    The in ear diaphragm of Voice of China is a metal composite diaphragm, which makes the three frequencies more balanced. It not only ensures that the high frequency band is more extended and the resolution of details is better, but also ensures the stability of the mid frequency, as well as the low frequency diving, bringing mellow mid tones and strong bass effects. 1MORE piston earphones are tuned by Grammy Award master Luca Bignardi. With the adjustment of professional masters, I believe that the sound quality of earphones is reliable.

After two days of trial, in terms of sound quality performance, the range of Voice of China 1MORE piston earphones and headphones is the same as that of the master tuning, but they do not have the pleasant sound effect of headphones. In ear earphones pay more attention to the reproduction of sound. The tri frequency is more natural and balanced, and makes the control of middle and low tones more excellent. In terms of sound quality, it can perform well without being warmed up. Like other 1MORE piston earphones, it is outstanding in the details of music.

Summary:

The quality of a headset should not only have the performance of sound quality, but also the comfort of wearing it. Everyone may have different feelings due to their different listening senses and sound sources. But whether it is comfortable to wear earphones is the most intuitive judgment. The ergonomic design of this Voice of China 1MORE piston headset and the attention to detail handling have greatly improved the wearing comfort compared with the previous headphones. In addition, the Voice of China 1MORE piston earphone performs best in the treatment of stethoscope effect among the earphones I currently use. When I didn't use the attached earphone clip, there was basically no stethoscope effect when I walked, only when I ran. This is nothing more than the wire processing of the 1MORE earphone. In addition, the earplug design of the Voice of China 1MORE piston earphone will keep a certain distance from the ear when used, without direct contact, which will more effectively reduce the contact with the body, and more effectively prevent the emergence of the stethoscope effect. The unique shape of the Voice of China 1MORE piston earphones has improved the comfort of wearing, especially in the treatment of stethoscope effect. It is worth having.
